Microcatheter Originating Debris during Neuroendovascular Procedures: Mechanism of Dislodgement and Its Prevention

American Journal of Neuroradiology

Microcatheter combinations investigated and the amount of debris they produced

Step	Side Port	Straight Port	RHV	Amount of Debris
Step	Side Port	Straight Port	RHV	Insertion	Extraction
1 SL-10 Evaluation	None	SL-10	Abbott	–	–
	SL-10	None	Abbott	+	++
	SL-10^{^a}^,^{^b}	Headway 21	Abbott	+	++
	SL-10	Prowler 21	Abbott	+	++
	SL-10 without guidewire	Prowler 21	Abbott	–	–
2 Microcatheter comparison(similar MC to SL-10)	Headway 17^{^a}	Headway 21	Abbott	+	++
2 Microcatheter comparison(similar MC to SL-10)	Echelon 10^{^a}	Headway 21	Abbott	+	++
3 RHV comparison (other RHV)	SL-10^{^b}	Headway 21	Boston Scientific	–	+

Note:—MC indicates microcatheter; – for amount of debris, none; +, identifiable; ++, substantial, "None" under Side Port and Straight Port, absence of device use.
